If you have coolant,
If the thermostat is good,
your fans come on,
It could be a water pump failure, it has a plastic impeller that sometimes can shell out.
I have a pic of a bad water pump for a Taurus below.
If yours has done this, and a piece is missing, see if you can find it stuck in the water passage on the engine side.
